EXERAUO Submersible LED Trailer Light Kit — DOT‑Sealed Boat Trailer Lights, 25 ft 4‑Pin Harness, License Bracket

EXERAUO Boat Trailer Lights Kit is a complete, waterproof LED lighting set designed for submersible trailer installations with a 4-pin harness and DOT-compliant sealed lamps.

Whether you're launching a boat, towing a camper, or outfitting a utility trailer, reliable lighting at the rear and sides is essential for safety and legal compliance. This EXERAUO kit bundles two rectangular sealed submersible lights, two amber side markers, an 11-LED 15" red light bar, a 25-foot 4-pin wiring harness, a license plate bracket and mounting hardware to give you a ready-to-install solution for trailers up to and over 80 inches in width.

How does this kit handle water exposure and corrosion?

The lights are built from ABS housings with polycarbonate lenses and use heavy silicone sealing to keep electronics dry when submerged. Components meet common DOT rear-lighting requirements, and the sealed design prevents water intrusion and corrosion on the LEDs and contacts.

• ABS housing with PC lens for impact and saltwater resistance
• Silicone-sealed electronics for submersion protection
• Marine-grade connectors on the included wiring harness

Which wires control which functions on the rectangular submersible lamps?

The rectangular submersible lights use separate colored leads for ground, running light, and brake/turn functions so each side operates correctly. Left and right sides share the same wiring scheme except for the turn/brake wire color difference.

• Left light: white = ground; white+yellow = brake/high brightness
• Left light: white+brown = running light/left license light (low brightness)
• Right light: white = ground; white+green = brake/high brightness
• Right light: white+brown = running light (low brightness)

Is the wiring harness easy to install and compatible with standard towing vehicles?

The kit includes an 18AWG, 25-foot 4-way flat connector wiring harness built to SAE J1128 standards, which plugs into common 4-pin vehicle sockets without cutting or splicing. This makes hookup straightforward for DIYers and reduces the need for additional adapters when connecting tail, turn, brake and ground circuits.

• 25 ft length for flexible routing to lights and vehicle plug
• 4-pin flat connector fits standard tow vehicle outlets
• Pre-terminated ends minimize electrical work and error

What applications and vehicles are these trailer lights suitable for?

This full LED lighting kit is versatile for many trailer types including boat trailers, utility trailers, campers, snowmobile trailers, and light commercial vehicles. The kit supports both under-mount and over-mount installations and is sized for trailers around 80 inches wide and larger.

• Designed for boat trailers, RVs, campers, and utility trailers
• Works for vehicles including pickups, vans, lorries, and caravans
• Includes license plate bracket and mounting hardware for quick fitting

Who is this for: The EXERAUO Submersible Trailer Light Kit is aimed at boaters, trailer owners and fleet operators who need a rugged, ready-made LED lighting solution that tolerates submersion and simplifies installation. If you value sealed, DOT-conscious lighting, a pre-built 4-pin harness, and a complete package that includes side markers and a license bracket, this kit reduces parts hunting and speeds installation for DIY mechanics and professional installers alike.
